You're all probably very well aware of this already but yup it's real. HUGtto's movie is a crossover with Futari wa Pretty Cure!!! Keep in mind, it's "Futari wa Pretty Cure" with no "Max Heart" on the end so unfortunately, Luminous will most likely not make an appearance or have that strong of a role. A news article even confirmed that Cure Black and White will be the only past Cures making a come back. Oh and yeah, I don't think "HUGtto! Pretty Cure The Movie♡Futari wa Pretty Cure" is our actual title yet so please, PLEASE do not go creating a page for this film just yet. If anything, please wait till around July for when the poster confirms the title.
While we're there, yup, the OP for Futari wa Pretty Cure is yet again, receiving a revamp, this time called "DANZEN! Futari wa Pretty Cure ~The One and Only Lights~" and will actually be the ending for the film. It'll be sung by our beloved Gojo Mayumi, if that wasn't obvious enough.
It also appears the film will be half in 2D and half in CGI, with the CGI parts being the other world the Cures meet in and will probably spend most the movie in. So in other words, the film will most likely be doing a Dream Stars.
